### RE: Third Submission of Supplemental Information to the 2012 New Source Review State Implementation Plan Submission

### :r~ Dear**M~nfeld:**



### Consistent with the provisions of Arizona Revised Statutes§§ 49-104, 49-106, 49-404, 49-406 and 49-425 and the Code of Federal Regulations (CFR) Title 40, §§ 51.102 through 51.104, the Arizona Department of Environmental Quality (ADEQ) hereby adopts and submits to the U.S. Environmental Protection Agency (EPA), the following supplemental information for the "State Implementation Plan

- New Source Review" submitted on October 29, 2012 (NSR SIP). ADEQ submitted previous supplements to the NSR SIP on September 6, 2013 and July 2, 2014.



### Delay in Action on R18-2-101(20), "Begin Actual Construction" Definition

Based on conversations between EPA and ADEQ staff, ADEQ understands that EPA believes the definition of "begin actual construction" in R18-2-101(20) is not consistent with EPA's definition of that term as interpreted by the agency. In addition, EPA has indicated that the definition does not qualify for partial disapproval, because it is not "separable" from the remaining rules, and that it is not appropriate for limited approval/limited disapproval. 1



### In order to provide time to continue discussions with EPA regarding this issue and to avoid
unnecessary delay in EPA action on the NSR SIP, ADEQ requests that EPA not act on the "begin actual construction" definition at this time. Please note that ADEQ does not necessarily agree with EPA's determination that the definition is not approvable and reserves the right to
comment on and challenge any later EPA disapproval of the definition.

1 SIP provisions are only "separable" if "disapproval of a provision will not affect the stringency of other portions of the SIP." 57 Fed. Reg. 13498, (General Preamble).

### Public Process for Proposed Final Permits

ADEQ's revised NSR rules allow an applicant for a Class I permit or Class I permit revision to begin actual construction, but not operation, of a source or modification on receipt of a "proposed final permit." In effect, under the revised rules, a proposed final permit is treated as

a final authorization to construct.

EPA has inquired as to whether the issuance of a proposed final permit constitutes a final, challengeable action under PSD/NSR. As discussed in the attached guidance memorandum, issuance of a proposed final Class I permit or permit revision constitutes an "appealable agency action" under Arizona administrative law and therefore may be the subject of an administrative appeal. An interested party would not have to wait for completion of EPA review and issuance of the final permit to file an appeal.



### Retention of Rules Not Replaced in SIP

ADEQ wishes to clarify that the Department is seeking removal of the existing elements of the NSR SIP identified in column 2 of Table 2-1 of the NSR SIP, as updated below, only where EPA
approves a replacement element into the SIP.

Specifically, as noted above, EPA has indicated that it cannot approve R18-2-101(20) as a replacement for the definition of begin actual construction in SIP rule R9-3-101(20), and we have requested that EPA not take action on R18-2-101(20) at this time. ADEQ therefore requests that SIP rule R9-3-101(20) be retained in the SIP until EPA does approve a replacement definition.

In addition, EPA has determined that the NSR SIP does not include replacements for the following necessary SIP elements:

R9-3-301(1) R9-3-301(K) R9-3-304(H) requirement for a preliminary determination degree of increment consumption visibility requirements

ADEQ therefore requests that EPA not remove these provisions from the SIP.



### Submission of A.R.S. § 

### 49-107, Local delegation of state authority

In the July 2, 2014 supplement, ADEQ relied on A.R.S. 

### § 49-107 as part of its identification, pursuant to 40 C.F.R. 

### § 51.162, of "the State or local agency which will be responsible for meeting the requirements of (40 C.F.R. Part 51, Subpart I, 'Review of New Sources and Modifications'] in each area of the State." A copy of that statute is included in this submission.

### Page 3of8

Submission of A.A.C. R18-2-334, Minor New Source Review

As the Notice of Final Rulemaking (NFRM) included as Appendix A to the NSR SIP makes clear, A.A.C. R18-2-334 was specifically included in the NFRM to comply with the minor NSR requirements of the Clean Air Act. That rule, however, was inadvertently omitted from Table 2-
1 of the NSR SIP, and as a result, the September 6, 2013 submission of "clean" versions of the proposed SIP rules did not include R18-2-334.

A copy of the clean version of A.A.C. R18-2-334 is included with the submission, and the revised version of Table 2-1 provided below includes a correction of this error.



### Revised Table 2-1

The following is a revised version of Table 2-1 of the NSR SIP, as updated in the July 2, 2014 supplement, reflecting the changes discussed above. As explained in the original SIP submission, rules identified by italics are applicable to both new and existing sources but are being submitted solely for purposes of major and minor NSR.

As·noted above, ADEQ requests removal of the rules, or separable portions thereof, identified in the second column of the table only where EPA approves a replacement element of that portion of the program into the SIP.

For sources seeking credit after October 11, 1983, for increases in existing stack heights up to the heights established under s ubsections (B)(2) and (3), either: i. A maximum ground-level concentration due in whole or in part to downwash, wakes, or eddy effects as provided in subsection (B)(6)(a), except that emission rate specified by any applicable SIP shall be used; or ii. The actual presence of a local nuisance caused by the existing stack, as determined by the Director; and c. For sources seeking credit after January 12, 1979, for a stack height determined under subsections (B)(2) and (3), where the Director requires the use of a field study or fluid model to verify GEP stack height, for sources seeking stack height credit after November 9, 1984, based on the aerodynamic influence of cooling towers, and for sources seeking stack height credit after December 31, 1970, based on the aerodynamic influenc e of structures not adequately represented by the equations in subsections(B)(2) and (3), a maximum ground-level concentration due in whole or in part to downwash, wakes, or eddy effects that is at least 40% in excess of the maximum concentration experienced in the absence of such downwash, wakes, or eddy effects. C. The degree of emission limitati on required of any source after the respective date given in s ubsection (A) above for control of any pollutant shall not be affected by so much of any source’s stack height that exceeds good engineering practice or by any other dispersion technique. D. The good engineering practice (GEP) stack height for any source seeking credit becaus e of plume impaction which results in concentrations in vi olation of national ambient air quality standards or applicablemaximum allowable increases under R18-2-218 can be adjusted by determining the stack height necessary to predict the same maximum air pollutant concentration on any elevated terrain feature as the maximum concentration associated with the emission limit which results from modelling the source using the GEP stack height as determined herein and assuming the elevated terrain features to be equal in elevation tothe GEP stack height. If this adjusted GEP stack height is greater than stack height the source proposes to use, the source’s emission limitation and air quality impact shall be determined using the proposed stack height and the actual terrain heights. E. Before the Director issues a permit or permit revision under this Article to a source based on a good engineering practice stack height that exceeds the height allowed by subsection (B), the Director shall notify the public of the availability of the demonstration study and provide opportunity for a public hearing in accordance with the requirements of R18-1-402.

R18-2-334. Minor New Source Review A. Applicability. 1. Except as provided in subs ection (A)(4), this Section shall apply to the following activities: a. Construction of any new Class I or Class II source, including the construction of any source requiring a Class II permit under R18-2-302.01(C)(4); or b. Any minor NSR modification to a Class I or Class II

source. 2. This Section shall apply toa regulated minor NSR pollutant emitted by a new stationarysource, if the source will have the potential to emit that pollutant at an amount equal to or greater than the permitting exemption threshold. 3. This Section shall apply to anincrease in emissions of a regulated minor NSR pollutant from a minor NSR modification, if the modification would increase the source’s potential to emit that pollutant by an amount equal to or greater than the permitting exemption threshold.4. This Section shall not apply to the emissions of a pollutant from any of the activities identified in this subsection, if the emissions of that pollutant are subject to Article 4 of this Chapter. B. No person shall begin actual c onstruction of a new stationary source, or minor NSR modificati on, subject to this Section without first obtaining a permit, a permit revision, a proposed final permit, or a proposed final permit revision from the Director in accordance with R18-2-304. C. The Director shall not issue a proposed final Class I permit or permit revision or a Class II permit or permit revision subject to this Section to a person proposing to construct a new source or make a minor NSR modificati on unless the source or modification meets one of the following conditions for each regulated minor NSR pollutant subject to this section: 1. The owner or operator elects to implement RACT.Arizona Administrative Code Title 18, Ch. 2 Department of Environmental Quality – Air Pollution Control

September 30, 2013 Page 57 Supp. 13-3 a. In the case of a new source, the owner or operator shall implement RACT for each emissions unit that has the potential to emit a regulated minor NSR pollutant in an amount equal to or greater than 20% of the permitting exemption threshold. b. In the case of a minor NSR modification, the owneror operator shall implement RACT for each emissions unit that will experience an increase in the potential to emit a regulated minor NSR pollutant equal to or greater than 20% of the permitting exemption threshold. c. When it is technically fe asible and otherwise consistent with the definition of RACT to apply the same devices, systems, process modifications, work practices or other apparatus or techniques to a group of emissions units, that group of emissions units shall be treated as a single emi ssions unit for purposes of subsections (C)(1)(a) and (b). The following are examples of situations towhich this subsection may apply: i. Emissions from a group of emissions units can be vented to a single control device. ii. A low-VOC coating can be used in several spray-painting booths. 2. An ambient air quality as sessment demonstrates that emissions from the source or minor NSR modification will not interfere with attainment or maintenance of a standard imposed in Article 2 of this Chapter. a. An owner or operator may elect to have the Director perform a SCREEN model of its emissions. If the results of the SCREEN model indicate that the source or minor NSR modification will interfere with attainment or maintenance of a standard imposed in Article 2 of this Chapter, the owner or operator may perform a morerefined model to make the demonstration required by this subsection. b. The requirements of this subsection shall be satisfied, if the results of the SCREEN or more refined modeling conducted pursu ant to subsection (B)(2)(a) demonstrate either of the following:i. Ambient concentrations resulting from emissions from the source or modification combined with existing conc entrations of regulated minor NSR pollutants willnot cause or exacerbate the violation of a standard imposed in Article 2 of this Chapter.ii. Emissions from the source or minor modification will have anambient impact below the significance levels as defined in R18-2-401. c. The assessment required by this subsection shall take into account any limitations, controls or emissions decreases that are or will be enforceable in the permit or permit revision for the source. D. RACT Determinations. 1. Except as otherwise provided in this subsection, the Director shall determine RACTon the basis of a case-bycase analysis performed by the permit applicant of the emission reduction methods av ailable for each emission unit subject to the RACT requirement under subsection (C)(1). 2. The Director shall accept a requirement proposed by a permit applicant as RACT under subsection (C)(1) if it complies with the mo st recently adopted of the following guidelines or standards in effectat the time of the application: a. A control technique guideline issued by the Administrator under section 108(f)(1) of the Act. b. An emissions standard esta blished or revised by the Administrator for the same type of source under section 111 or 112 of the Act after November 15, 1990. c. An applicable requirement of this Chapter or of air quality control regulati ons adopted by a County under A.R.S. § 49-479 that has been specifically identified as constituting RACT. d. A RACT standard imposed on the same type of source by a general permit. e. A RACT standard imposed on the same type of source under this Section no more than 10 years before submission of the application by the permit applicant. To facilitate identification of previously imposed RACT standards, the Director shall establish an online database of RACT determinations made under this Section. E. Notwithstanding an election toadopt RACT under subsection (C)(1), a permit applicant subjec t to this Section shall conduct an ambient air quality impact assessment under subsection (C)(2) upon the Director’s request. The Director shall make such a request, if there is reas on to believe that a source or minor NSR modificati on could interfere with attainment or maintenance of a standard imposedin Article 2 of this Chapter. In making that determinati on, the Director shall take into consideration: 1. The source’s emission rates. 2. The location of emission units within the facility and their proximity to the ambient air. 3. The terrain in which the source is or will be located. 4. The source type. 5. The location and emissions of nearby sources. 6. Background concentrations of regulated minor NSR pollutants. F. The Director shall deny an application for a Cl ass I permit or permit revision or a Class II permit or permit revision subject to this Section, if an assessme nt conducted pursuant to subsection (C)(2) demonstrates that the source or modification will interfere with attainment or maintenance of a standard imposed in Article 2 of this Chapter. G. An application for a permit or permit revision subject to this Section may be processed as a minor permit revision if one of the following conditions is satisfied for each pollutant subject to subsection (C): 1. A RACT standard is imposed under subsection (D)(2) on each emissions unit that re quires such a standard under subsection (C)(1). 2. The results of the SCREENmodel for a regulated minor NSR pollutant show expectedconcentrations, including background concentrations, that are less than 75% of the applicable standard imposed in Article 2 of this Chapter. H. A copy of the notice required by R18-2-330 for permits or significant permit revisions subject to this Section must also be sent to the Administrator through the appropriate regional office, and to all other state and local air pollution control agencies having jurisdiction in the region in which the source subject to the permit or permit revision will be located. The notice also must be sent to any other agency in the region having responsibility for implementing the procedures required under this subpart. I. All modeling required pursuant tothis Section shall be conducted in accordance with 40 CFR 51, Appendix W. J. The Director shall specify thos e conditions in the permit that are implemented pursuant to thisSection.

The issuance of a permit or permit revision under this Section shall not relieve the owner or operator of the responsibility to comply fully with applicable provisions of the SIP and any other requirements under local, state, or federal law. L. Delayed Effective Date. This Section shall take effect on the effective date of the Administrator’s action approving it as part of the state implementation plan.
Historical Note New Section made by final rulemaking at 18 A.A.R. 1542, effective August 7, 2012 (Supp. 12-2). ARTICLE 4. PERMIT REQUIREMENTS FOR NEW MAJOR SOURCES AND MAJOR MODIFICATIONS TO EXISTING MAJOR SOURCES
R18-2-401. Definitions The following definitions apply to this Article: 1. “Adverse impact on visibility ” means visibility impairment that interferes with the management, protection, preservation, or enjoyment of the visitor’s visual experience of a Class I area, as determined according to R18-2- 410. 2. “Baseline actual emissions” means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with subsections (2)(a) through (c). a. For any existing electricutility steam generating unit, baseline actual emissions means the averagerate, in tons per year, at which the unit actually emitted the pollutant during any consecutive 24-month period selected by the owner or operator within the five-year period immediately preceding when the owner or operator begins actual construction of the project. The Director shall allow the use of a different time period upon a determination that it is more representative of normal source operation.i. The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions. ii. The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above any emission limitati on that was legally enforceable during the consecutive 24-month period. iii. For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period must be used to determine the baseline actual emissions for the emissions units being changed. A different consecutive 24-month period can be used for each regulated NSR pollutant. iv. The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by subsection (2)(a)(ii).b. For any existing emissions unit (other than an electric utility steam generating unit), baseline actual emissions means the average rate, in tons per year, at which the unit actually emitted the pollutant during any consecutive 24-month period selected by the owner or operator within the 10-year period immediately preceding either the date the owner or operator begins actual construction of the project, or the date a complete permit application is received by the Administrator for a permit required under 40 CFR 52.21 or by the Director for a permit required under the state implementation plan, whichever is earlier, except that the 10-year period shall not include any period earlier than November 15, 1990.i. The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions. ii. The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive 24-month period. This provision applies to excess emissions associated with a malfunction. iii. The average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major source must currently comply, had such major source been required to comply with such limitations during the consecutive 24-month period. However, if an emission limitation is part of a maximum achievable controltechnology standard that the Administrator proposed or promulgated under 40 CFR 63, the baseline actual emissionsneed only be adjusted if the state of Arizona has taken credit for such emissions reductions in an attainment demonstration or maintenance plan submitted to the Administrator pursuant to section 110(a)(1) of the Act. iv. For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period must be used to determine the baseline actual emissions for all existing emissions units affected by the project. A different consecutiv e 24-month period may be used for each regulated NSR pollutant.v. The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by subsection (2)(b)(ii) or (iii). c. For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit’s potential to emit. d. For a PAL for a stationary source, the baseline actual emissions shall be calculated for existing electric utility steam generating units in accordance with the procedures in subsection (2)(a), for other existing emissions units in accordance with the procedurescontained in subsection (2)(b), and for new emissions units in accordance with the procedures contained in subsection (2)(c). 3. “Basic design parameter” means:a. Except as provided in subsection (3)(c), for a process unit at a steam electric generating facility, the owner or operator may sele ct as its basic design parameters either maximum hourly heat input and maximum hourly fuel cons umption rate or maxi-
